Electrical Problem

I just got everything put back together, new wiring harness, bulbs, etc. My problem: I've got everything working ie blinkers, brake lights headlights front sidemarkers etc. but my rear tailights (for night driving) dont come on and my sport lamps wont work either. Any suggestions? The only thing I didn't replace was the sport lamp switch (can't buy new) and the headlight switch.

Any help would be greatly appreciated. Thanks.
